ZTW Seal 90A SBEC G2 32-Bit Waterproof ESC 3-8S with Water Cooling for RC Boats and Marine Propulsion

32-Bit 170MHz for Precision Throttle Control

Powered by a 32-bit microprocessor at 170MHz, the Seal 90A G2 delivers lightning-fast computing and ultra-smooth throttle linearity. Whether navigating mid-size RC catamarans or light industrial subsea thrusters, the response is immediate and predictable.

85A Continuous / 95A Burst on 3-8S

Next-generation MOSFET technology ensures low heat generation and high reliability under instant current loads. With 85A sustained and 95A peak across a 3-8S range, this ESC unlocks higher top speeds for RC boat enthusiasts and more thrust for small commercial marine vehicles.

IP67 Waterproof + Dual-Channel Water Cooling

The IP67-rated sealed enclosure withstands full immersion, while two water-cooling pipes with custom heat sinks efficiently dissipate heat — a critical advantage for boats that run hard and ESCs mounted in confined motor boxes.

8A Adjustable SBEC for Servo-Heavy Setups

The 6.0/7.4/8.4V switching BEC delivers 8A, powering multiple standard servos on boats with dual rudder, trim tab, and reverse setups — no external UBEC required.

Forward/Reverse & Freewheeling

Switch between "Forward Only" racing mode and "Forward and Backward" for scale operation and docking. Freewheeling circuitry boosts driving efficiency and extends runtime by reducing parasitic drag when off-throttle.

Full Protection Suite

Over-temperature power reduction, low-voltage cutoff, start-up, signal loss, phase loss, over-current, abnormal voltage, and over-load protection safeguard your investment in every operating condition.

Telemetry & G2 Programming

Real-time telemetry (current, voltage, temperature, RPM, throttle, status) via ZTW App or LCD Program Card G2. Full parameter configuration through Bluetooth app, LCD card, or transmitter.
